Do you have an AntiVirus enabled ? a firewall ? some VPN ?  
What is your OS ?  
Are you in a country or with a internet provider who restrains Tor usage ?

The day I installed the bisq connected normally and I sent some btc to the wallet and made a sale offer. The next day started to give this problem, already rotated the internet from my mobile and still without connecting. On my work computer I have another wallet that works normally on fedora 30. Here in my house is windows 10, Brazil.  
I already uninstalled, deleted the backup and reinstalled, but nothing worked.
